It's an old custom to write down your request and put the note in one of the cracks in "Wailing Wall" (also known as "Western Wall", "ha-kotel ha-ma'aravi"). Once this was done the request should be granted by god. These notes are collected from time to time and are burried as holy artifacts.
Using modern technology, you can send us your prayer by e-mail. We will print it and insert it into one of the cracks of the wall.
In Shemot Rabba, a midrashic collection of exegeses on the book of Exodus from the seventh or eighth century C.E., we find the saying attributed to Rabbi Acha (himself a fourth-century scholar) that, even after the destruction of the Temple, "the Shekhinah [God's presence in the world] never leaves the Western Wall."
The Western Wall is the lower part of the wall of what was the Jewish Second Temple.
It is often called the Wailing Wall by Christians to describe the Jews who came to grieve at the scene of the temple area. But the term offends many Jews.
The Temple Mount is the name Israelis give to the area above the wall - where Islam's third holiest shrine, the Aqsa Mosque now stands - because somewhere in there are the remains of the Second Temple of Jerusalem which was destroyed by the Romans in 70 A.D. As such it lies at the heart of the Jewish faith. In the centuries that it stood, the first and then the Second Temples were the epicentre of the Jewish faith.
The Wall is all that is left of the Temples. Every Friday, thousands of Israelis head for it in the afternoon at the start of the Sabbath to pray, and leave messages and prayers in the crack of the wall.
Hundreds of prayers are put into the cracks of the wall.
The surface of the wall, from the pavement and up to the man's height, differs by the color and feels differently - it is polished by human hands that touched it in prayers through the centuries.
